The present study aims to investigate the impact of clay deposits and organic fertilizer on water characteristics, cumulative infiltration and intermittent evaporation of loamy sand soil. Soil sample was collected from surface layer (0-30 cm depth) of the Agricultural Experiment and Research Station ...
Soil moisture recorded an increase ranged from 19.1% to 22% and decrease with increasing of ages. Soil texture of silt higher than clay and sand; (2) Soil tension tend to be decreased from 36.2 kPa in 1-years-old to 9.17 kPa in 5-years-old and increase when the soil depth become ...

of 0.4mg/kg, indicating that the geological background in the area was closely related to the soil selenium content. The Se-enriched soil in the area was mainly controlled by the Emeishan basalt Formation, which contained basalt intercalating with picrite and tuffaceous sand and mudstone. (2)...
Liquefaction of sand soil such as silty sand was quite popular in earthquake. Gravel liquefaction, by contrast, was seldom. Soil liquefaction was popular in Chengdu Plain in Wenchuan Earthquake and there was ejeched gravel in several sites. Through drilling and tests for typical liquefied sites, ...
of salt leaching,high content of nutrients.Myricaria laxiflora,on the other hand, prefers the alluvial soil with sand and gravel in subtropics climate.The soil is of weak alkalinity, has low content of nutrient but moderate salt.The soil at the re site reserve in Wuhan Institute of Botany ...
The optimal conditions for surface sediment P adsorption were obtained from the RSM, as follows: the disturbance frequency of 138 rpm, the water column P concentration of 1.14 mg L−1, the pH of 7.76, the ionic strength of 0.02 mol L−1 and the water-soil ratio of 5.67:1, and the...

computer programming language tools were used to create map coverages of soil properties including soil texture and rock fragment classes, depth-to-bedrock, bulk density, porosity, rock fragment volume, particle-size (sand, silt, and clay) fractions, available water capacity, and hydrologic soil ...
sand dunes are different in grain size to a certain extent and the mineral compositions of dune sand are dondnated by stable and extreme stable minerals, with high stability and maturity.Aeolian sand in the region mainly comes from the reachvation of ancient sand dunes, the transportation of ...
